Toscanini conducted the Flute of San-Souci with the New York Philharmonic on 3, 4, 5 (Students concert) and 6 December 1931
The other items of the concerts were J.C. Bach Sinfonia in E-Flat major, Mendelssohn Reformation and Pizzetti's Concerto per l'Estate.
From the New York Philharmonic Program. Die Flote von San Souci, the suite for chamber orchestra on this program. was publishd in 1930. Ther is no programmatic guide to the music, no preface or other explanation of the significance of the title. But the bearer is probably justified in associating Herr Graener's musical fantasy with the royal flautist Frederick the Great, and one of his favorite diversions at "Sans Souci", the little palace which be built for himself at Posdam.
I do not know the reasons
,
apart from the purely musical ones, for which Toscanini conducted that music on 1938. But he also continued to conduct the music of Richard Strauss ( I say this for the reasons quoted below).
Dell'Arte CD: "However, it was on September 22nd 1933, that Adolf Hitler signed a decree empowering the Ministry of Propagandato establish six Reich Culture Chambers for literature, press, radio, theatre, music and fine arts. The Reichmusikkammer was organised by Dr. Joseph Gobbels, the aim being to supervise the aesthetic and racial "problems" od German music. Richard Strauss was named as President, Pauld Graener, Vice President and Wilhelm Furtwangler, General Music Director. Graener held the post until 1941 and died in Salzburg in Nove,mber 1944, aged 72. Given Graener's prestigious position in Hitler's Third Reich, Toscanini's open hostility to Nazism and exact date of this particular broadcast, it is perhaps surprising that the performance took place at all - although it should in all fairness be pointed out that the piece was already in Toscanini's repertoire, (he had played it with the New York Philharmonic in 1931, two years before Hitler came to power).
"The evening otherwise brought to attention Graener's charming and nostalgic suite, 'The Flute of Sans Souci'. John Wummer was the solo flutist of the Graener's work, which admirably recaptures the spirit of the 'Gallant Style'. The New York Sun, Monday, November 7, 1938."
Probably
Toscanini mainly cared about the beauty of music, regardless of political
situations. Just as it happened when in 1916 he conducted the
music of Wagner, despite the bombing of Padua.
